SPECIFICATION forming part of Letters Patent No. 442,677, dated December16, 1890.

Application filed June 23,1890. Serial No. 356,498. (No model.)

To all whom it may concern:

Be it known that I, JAY \V. FRY, a citizen of the United States,residing at Lake Forest, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Smoke Consumers orBurners; and

I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, forming a part hereof, in which Figure lis a side elevation, partly in section,showing the apparatus applied toa fur- 1 Figz2 isa top or plan view,

and plans; but in practice it has been found that none of theseappliances perform the work required in a satisfactory manner and so asto produce perfect results, and this is especially true in fresh firing,as the new coal makes a greater amount of smoke than the steam or steamand air blast can dispose of, the result being the emission of heavyblack clouds of smoke from the chimney, and such emission will continueuntil the smoke produced becomes less in quantity and so that the blastwill act thereon. The cause for this is readily found in the fact thatthe blast is so much lighter than the fresh smoke that it cannot cut andbreak the smoke, and, furthermore, the natural tendency of the steam isto rise and seek to escape, so that with a fresh firing the blast,instead of acting as a check and retainer of the smoke, is a means forinsuring its discharge, as the blast will naturally seek an outlet andthe smoke will follow. It is well known that with a heavy and moistatmosphere smoke will be forced to the ground and cannot rise, owing toits being so much lighter than the moist atmosphere, and it is furtherknown that heat is intensified by the application of water, and heat isthe best consumer of smoke. The object of this invention is to utilizeas a smoke-consumer the effects of a moist atmosphere in holding thesmoke in the firebox and over the fire until the carbon in the smoke hasbeen consumed for the smoke to escape without the heavy blackappearance, and a further object is to secure the benefits of wettingdown the tire to increase the heat; and to these ends the nature of theinvention consists in projecting over the fire a blast of air chargedwith moisture, and in the several parts and combinations of partshereinafter described, and pointed out in the claims as new.

In the drawings, A represents a blast-fan, having a discharge a, asusual, and which may be of any well-known form of construction.

B is a pipe connected with the discharge a of the fan by anelbow-coupling a and an attaching-pipe a", and also connected with aT-coupling b by an elbow-coupling, and attached to the coupling 1) is ashut-off valve 1), connected to a pipe I)" by an elbow-coupling, whichpipe b" leads into the water-reservoir.

O is the water-reservoir, which reservoir, as shown, stands vertical,but could be placed horizontal, if desired. This reservoirC has adischarge-pipe 0, connected by an elbow-coupling with a shut-off valve0', and is provided with a blow-off cock 6 and an air-vent e.

D is a pipe connected with the T-coupling b and having a T-coupling dfor attachment of the shut-off valve 0 and having a shutoff valve (1'. i

E is a pipe connected with the pipe D by an elbow-coupling.

F are two pipes connected with the pipe E by a Y-couplingf.

G is a pipe formed, as shown, of a series of short sections connectedtogether by T-couplings, and, as shown, two of these couplings receivethe pipes F,which couplings g are located on the pipe G at the properpoints for the attachment of the pipes Fone on each side of thelongitudinal center of the pipe G.

H is a tube in which is located the pipe G. This tube H is open at eachend, and, as shown, is formed of a number of sections connected togetherby couplings h, each of which has on the rear side an opening h for thead mission of air, and air also flows in at the open ends of the tube H.

I are discharge-nozzles for the pipe G. The intermediate nozzles I areattached to the T- couplings 2, which connect the pipe-sectionstogether, and the end nozzles I are each attached to the end of the pipeG by an elbowcoupling 1'. The pipe G, instead of being formed ofsections, can be a single piece, in which case the couplings g and i ican be dispensed with and the pipes F attached by a stuffing-box orother suitable means, and the nozzles I screwed directly into the pipe Gor into suitable bosses on such pipe, the ends of the pipe G beingclosed by caps or by plugs to insure the discharge from the pipe Gthrough the nozzles I.

J are discharge blast tubes, one for each discharge-nozzle I, the nozzlejust entering its discharge-tube, as shown in Fig. 2. A blast-tube isentered into each coupling h in the arrangement shown, and the dischargeend of each tube J is flattened or spread so as to present a wide mouthj, by which the blast will be spread out over the fire. The tube H,instead of being formed in sections, can be a single piece, in whichcase the couplings h can be dispensed with and the openings h formed inthe body of the tube II, and the discharge blast-tubes J be entered intothe tube direct or into bosses on the tube 11, or otherwise attached in.position to receive the discharge from the nozzles I.

K is a furnace, having grate-bars 75, as usual, for the fire, and overand onto which the blast is to be projected from the blast-tubes J.

L is a water-supply pipe, leading from a tank or other source of supplyinto the waterreservoir C, and having a shut-off valve l to regulate thesupply and the filling of the reservoir C.

The blast-fan, as shown, is located overhead and is to be driven in anyWell-known manner of driving such fans. The pipes B,D, E, and F form, infact, a continuous pipeleading from the fan A to the discharge-pipe Gfor delivering the blast created by the fan to the pipe G, to bedischarged therefrom through the nozzles I into the tubes J and over thefire, and the arrangement of pipes shown is only for the purpose ofshowing the connection with the overhead fan A and the dischargepipe G;and it is to be understood that a single pipe in one piece or a singlepipe of sections arranged differently from the sections B, D, E, and Fcan be used, so long as such pipe furnishes a communication between thefan and the discharge-pipe G, and the blastfan A can be located on thefloor or other support, and the supply-pipe therefrom to the pipe G andthe Water-reservoir G can be placed horizontal instead of perpendicular,with the proper connections therefor. The discharging blast-tubes J aremade to project just through the wall of the furnace, and as many ofthese tubes and of the discharge-nozzles I are to be used as requiredfor the size of the furnace, a sufficient number being provided tosupply the quantity of air and moisture to hold the smoke. The air fromthe fan A will pass into the pipe D when the valve 1) is shut and thevalve (1' is open, and will be combined with water from the reservoir 0,which flows into the pipe d when the valve 0' is open, and the combinedair and water will pass through the pipes E and F under pressure intothe pipe G and be forcibly discharged in the form of spray through thenozzles I into the tube J, and be comniingled in the tubes J with theair from the tube H, moistening such air, and this moist air will beprojected and discharged over the fire from the tubes J, forming a heavymoistcanopy which will effectually hold the smoke against rising and forthe heat to consume all the carbon to an extent sufficient to preventthe emission of black smoke. The blast of air can be regulated by thevalve (1, and the discharge of water from the reservoir can be governedby the valve 0, and if more pressure is wanted in the reservoir to givea more rapid flow of water from the reservoir it can be readily had byopening the valve 1). The heat of the furnace will produce a suctionthrough the tubes J, which extends into the tube H, and this suctiondraws air .from the outside into the tube II at the ends and through theopenings h, and this air will, by the suctionin the tubes H and thedischarge from the nozzles I, be drawn rapidly through the tubes J andin its passage be thoroughly moistened by the waterspray of the nozzlesI, and this moistened air will be discharged at the mouths of the tubesJ and be projected over the fire to act on the smoke, asabove described.The moist air delivered over the fire forms in effect a heavy cloud bywhich the smoke Will-be caught and held in the fire-box of the furnace,and atthe same time the moisture is not sufficient to quench the fire,but acts to intensify the heat, thereby increasing the combustion of thesmoke. The tube H gives a constant supply of fresh air to supportcombustion,and,if desired, the openings h of this tube II can besupplied with dampers to regulate the amount of air admitted to becharged with moisture, and the blasttubes J are to be of a sufficientlength to insure the charging of the air of the tube H with moisturebefore entering the furnace. The reservoir 0 can be supplied with awater-gage M, by means of which the stage of the water in the reservoircan be determined without any trouble, and the ventopening 6' can bedispensed with and the air vented in filling the reservoir by openingthe valve 19' and leaving the valve slightly open to insure a dischargefrom the reservoir into the tube D.

The apparatus is very simple, and can be applied to furnaces without anytrouble, as all that is necessary is to insert the tubes J through thefurnace-Wall in proper position to project a blast of moistened air overthe fire, and in use the apparatus will be found efficient as a meansfor consuming the smoke and in case a blast of air only is wanted it canhe had by simply closing the Valves 1) and 0, when the air alone willpass from the fan to the discharge-pipe G and be projected over thefire.
